SAO PAULO — Brazil’s jailed former President Luiz Inacio Lula da Silva pledged on Friday to block or undo privatizations if he is returned to the office he held from 2003 to 2010.

Da Silva will likely be barred from running for the presidency again by Brazil’s electoral court, but his statements are seen as the program of his left-leaning Workers’ Party ahead of October’s elections.

In an article published in the newspaper Correio Braziliense, da Silva said he would reverse the ongoing process to privatize state-run energy company Eletrobras. He also criticized politicians who contend that oil giant Petrobras needs to be sold.

Unpopular President Michel Temer has pushed forward with plans to sell Eletrobras and several members of his administration believe Petrobras should be privatized.

Da Silva also criticized Temer’s decision to allow a joint venture that gives Boeing control of Brazilian plane-maker Embraer. The former president vowed to halt the move.

Da Silva leads the polls despite his corruption and money laundering conviction. He can still appeal the decision, which he deems to be political persecution.

“I have the historical obligation, no matter what my personal circumstances now, of conducting our country to a reencounter with democracy and sovereignty, with a clear commitment to revoke through a popular referendum every measure that damages our independence,” da Silva wrote.

Media in Brazil media have reported that former Sao Paulo Mayor Fernando Haddad is the Workers’ Party favourite to replace da Silva as candidate if the former president is indeed barred.

Brazil’s October election will take place on Oct.7.

Though a member of another party, left-leaning presidential hopeful Ciro Gomes is seen as a potential heir to da Silva’s votes and also made the same anti-privatization pledges a few weeks ago.

In a letter to Boeing, Gomes said it is “a grave inconvenience” that Embraer is bought 100 days before Brazil’s presidential elections.

Earlier this week, a state-run energy company in the state of Piaui was sold in what was considered the kick-off of the process to privatize Eletrobras.

Members of the Temer administration say the measure is necessary so Brazil can reduce its budget deficit and boost its private sector, while critics believe selling Eletrobras will give the country’s waters away to foreign companies. Brazil’s main energy source is hydroelectricity.
